The Phil's Photo catalog (phototype) called it Dempsey Medium. The only other digital version I'm aware of is Thomas E. Harvey's 'JoeLouis'. That was from 1992 and may be tricky to find. It also uses what was Dempsey's alternate 'S', which is different from the default 'S' in your image.

Kevo: QBF is short for The Quick Brown Fox Co., was a company distributing photolettering typefaces, I have one of their catalogs, it's a good resource for identifying typefaces from before the computer era.
